Mommy makeover plus rhinoplasty? Is it safe? Is 6 hours enough time for both?

Hello Doctors out there! I am scheduled to have an a Lipo-tummy tuck, a breast lift (NO implants,) and a rhinoplasty. The rhinoplasty is to remove dorsal hump and fix drooping tip. My procedure is set to take five hours and 45 minutes, or at least that is the time booked. The doctor has wonderful reviews online and amazing before and after pictures. However, I am getting nervous now that my procedure is less than a month away. I am going to be under twilight anesthesia, which is what I prefer. But I am getting afraid of having anesthesia toxicity or worse. I think I’m just having anxiety, but I was just wondering if it is possible to do all these procedures under six hours ? Is my surgeon being ambitious? Or if he thinks that he can do it under six hours, should I just trust his judgment? Like I said, I already paid for the procedure and this doctor is highly recommended via real self, and his before, and after pictures are amazing. Please let me know your thoughts.
